2.2 Role of Physical Evidences in Administration of Justice

1. The investigation's compass — the leads-and-links (the suspect's connection, the modus's pattern). 2. The prosecution's proof — the case's scientific spine (the identification, the reconstruction). 3. The defence's shield — the alibi's-and-exclusion's evidence (the innocence's exonerations). 4. The court's certainty — the beyond-reasonable-doubt's scientific support. 5. The error's corrector — the miscarriage's undoing (the wrongful-conviction reversals — the DNA exonerations' global record). 6. The plea's reality — the guilty pleas negotiated on the science (the trial's avoidance).
